Make sense to change filters after minimal use?

Oh, the "experts" are nagging again. Is there any logic to changing machine filters when they are at only a fraction of capacity? With canister filters, I think there is a tenancy to toss filters without any thought to the amount of load material in them. This is the equivalent of tossing a P1 filter at 3k miles in a clean running Honda.

So, the "experts" never cut filters open, but KNOW it's BEST to change them constantly, even 2x as often as oil. Since I cut a few open, I realize there is MINIMAL loading in my apps, so I occasionally re-use them.

Is there a right and wrong position? I mean, isn't it smarter to change at the right time, maybe 50%. These guys talk about the "risk" of running from say the 10% capacity they actually use....twice as long to say 20%. I think it's just fear of the unknown, ignorance and not wanting to contradict their beliefs they got from their peers group.

You have some good points, argueably. However, in paying under $6 for a PureONE, it feels good knowing that the filter is as fresh as my oil, and, if for some unforeseen reason, I have to extend the next OCI, it will have begun with a new filter. (Boy Scout stuff).

I read a "Lube-tip" in an issue of Machinery Lubrication I just got and it said that you might see a spike in particle count after changing out a filter in a lube system due to the 'distrubance' of changing the filter. They recommend changing filters only they've reached their contaminant capacity or the manufacturer's recommendeed service life.

Filter Changes Can Disrupt Particle Counts
This technical tip was submitted by Brian Mann, a rotating equipment specialist at ConocoPhillips:

"Have you ever seen a sudden spike in particle count for a stable circulating oil system, where no oil has been added or lost? Check to see if the oil filter was changed just prior to the oil sample date. It is not uncommon for a spike in particle count after changing oil filters due to the 'disturbance' to the system. Therefore, don't be too zealous in changing filter elements purely on a calendar basis. Take full advantage of the operating life of your elements, and only change them when they have reached their load capacity or have been in the system up to their manufacturer's recommended service life."

Looks like you found it too.
